For more information on video game vocabulary, refer to the Glossary of video game terms on Wikipedia.

A

Avatar

Simply a homin(a). Its «anima» is the player behind the character; could be its conscience, its soul...

B

Beer

Trykers are brewing Byrh, for sale at the bars of Fairhaven and Avendale

Bird

There are no birds on atys, but there are winged creatures; Izams, Igaras, and Yber are Avians, and the "Javings" are Javans.

Blood

Purists are fighting each other on this point... is there blood in the bodies of homins or not? Homins can be considered to have both blood and sap, but the word "sap" may be preferred as a general rule. (While there is no agreement on the question, there is very little doubt about the humanoid origin of the Atysian races...)

C

Chatlog

Trykers invented a device, the Tyllidolh‎, to record conversations.

Chivalry, Chevalerie

By definition, these words cannot exist, since there are no horses in the Atys Fauna. See also Horse, Horseman. Knight and Knighthood, which etymology don't refer to horse seem acceptable though.

computer

See PC.

D

Disconnections (untimely disconnections)

Tepsen's disease.

Dog 

(animal) : There are no dogs but Gingos, Torbaks...

E

Earth

We are not on Earth, my good homins! Prefer the term "Bark" to the word earth. Ex: "On the whole Bark", and not "On the whole Earth"... As the Earth was mentioned by Karavan, we can talk about it as the first planet created by Jena, but to make it more RP-ish (the correct spelling is unknown to Homins), we deform the spelling, for example: Errth, Earf, etc....

F

Fame

(NOP in English)

Fish

Not a prohibited name, but names such as: Sagass, Prakker, Hachtaha, Baldusa, Clap-clap should be preferred...

G

God

Delicate concept, rather swear "By Jena", or "by Ma-Duk", "By the Great Mentor, the Great Dragon (The Fyrak if you're Fyros), the Great Glouglou.

H

Horse, Horseman

Your mounts will not be powerful horses, but Mektoubs or Gubanis, animals used both to transport goods and to move around. Who rides a Mektoub (a Gubani) is therefore a mounted warrior, or rider, a Mektoubier (a Gubanier),

HRP

see IRL,

Humanity

No so very dear, not humanity but "hominity"! Nuance....

Human

No known humans on Atys. We're talking about homins..

I

IG

To be "In Game" is to be on the Bark.

IRL

if being IG is to have your feet firmly on the Bark, as opposed to the IRL that you could also write IRreaL, it is to have your head outside "In Real Life." Having your head in the air, being in the moon, in the clouds? So, IRL, couldn't it be beyond canopy?

J

K

Keyboard

The carapace of arma does the job very well.

Knight, Knighthood

See Chivalry.

L

Language IRL (German, French, Spanishl...)

Dialect (Atysian). In Taki Zorai, we could say "Taki Shizu"

Level

Aaargh! What's less RP-friendly than talking about "level"? instead, use "skill" and talk about "circles" to define your level. For example, "My skills reach the seventh circle of magic proficiency." Okay, it's longer than "I'm lvl 70," but it's so much more beautiful... You can also use won titles such as "Master Forest Forager".

M

Man

Neither woman nor man, but homine and homin.

Mask

The Zoraï wear a mask, but it is genetically linked to the Zorai's face, so there is no question of saying: "you must be ugly under your mask" since this mask is the face...

Metal / iron...

No metal! No metal! Like stone, metal does not exist on Atys (in short, everything is alive or has been alive!). Only Karavan has metal, but it does not come from Atys....

Mob

Predator, Prey, Kitin, insect... or better, the name (varinx, kincher etc.)

Moon

We should avoid talking about moon, but about the "star of the night" instead. There are several celestial objects around Atys, three of which could be called "Moon". See Astronomy.

N

Nobility

No nobility for the newly returned homins from Exodus. To be in compliance with the background designed by the game developers, you must not give yourself any title of nobility. Make your story a legend, an old paper found in one of your attics, wrap it all in mystery and you may not be out of Ryzom's background...

Nair

Nair- is a Tyll prefix used as a honorific mark of respect.

O

Online

See IG

OOC

See IRL,

P

PC

The Matis received the Karavan interface module with Atys. Fortunately, everyone can use it on the Bark.

Pet

It seems that they are Zigs: yubo, gubanis or frippos.

Photograph

The word "luciogram" (lucio in short) is often used to define a screenshot. See also Luciography

Q

R

Rat 

(animal) : There are no rats but Ragusses...

(insult) : Generic vocable. No need to blame these "Fyros rats", it doesn't mean anything. Prefer ragusses, bodocs or caprynis. Valid for "pig" or other empathies....

RP

Useless to say it as soon as we are on the Bark.

S

Sand

There is no sand on Atys since there is no stone... but on the other hand, sawdust and ashes. Nevertheless, it seems that in the Lakes, it is indeed sand (the result of the crushing of the shells and corals).

Screenshot

See Luciography, Lucio, Luciogram

Ser/Serae

A typical Matis mark of deep respect invented (we will say found) by the guild Hesperian. Ser is a bit like Sir or Monsignor, but with a female equivalent (Serae). It is used as such. For example: "Ser Karouko, I respectfully greet you on behalf of Serae Aliciae Drosera who engages you in the work you have undertaken with such ardour ...".

Stone

No stones on Atys (at least on the surface), everything is made of solidified, crystallized, frozen or coagulated sap, at your convenience. But walls or stone statues.... none!

Study of Kitins' origin

Paleokitinology.

Sun

One should avoid talking about sunlight, but rather about "star of the day" or "luminaire". See Astronomy.

T

Tell

This is a channel that raises some concerns: RP or not RP? In fact, the "tell" could be, depending on the case, an inaudible whisper for others (RP) or simply and generally a "private conversation" (HRP).

U

V

W

Wiki

EncyclopAtys, The Great Library, which pages are Ambers or Amber Cubes.

Woman

Neither woman nor man, but homine and homin.

Woren Siloy

Contraction of Woha (Zoraï), ren pyr (fyros), Deles Silam (Matis) ad Lordoy (Tryker), an abbreviation used by pacifists to address a multiracial meeting.

WWW

(World Wide Web) why not use the word "Web instead of WWW to stay closer to the Atysians'language?

X

XP

Why not talk about strength or experience? "Oh, that varinx was really very strong" or "I gained a lot of experience killing it!"

Y
