What is a roleset on roblox

i think a roleset is a set(group of medels put together) with a roleplaying game
Roleset: A roleset is the ranking in a group, for example in Korblox's Empire, Korbloxians is a roleset. Rolesets are added by BC's, TBC's, and OBC's for his/her group by purchasing them with robux.

-I would know this, because I was just check9ing how much a roleset cost.
