I've spent days coming up with a role for a character. Not my best ever, no role contest win or anything....

But a specific, intended, feature of it will be it's length. (Especially because it is intricate and has many facets)

But, I would hate to plan out a role only to find out later that I'm over the limit length wise...either per role chapter or number of chapters.....especially since I always like to plan character growth via role additions as the character ages.

I can not find it listed anywhere the limits...

Either character or line limit per chapter ...or number of chapters.

Could it be possible to get some idea of the limits I am working under, so I can start crafting the shape of the role?

I'm not quite sure what the limit is per individual role entry (in terms of lines/characters), There is no chapter limit unless you're abusing the command (per Nalasul). In this case, you're clearly not. You just have a longer than average role, and that's fine.

If you're using mudlet, you can use the formatter to get a reasonably sized chunk for a 'chapter' and then use the 'role queue' command to queue it up. Once you 'role send', if it's too long, it should tell you. You can edit the size of your chapters accordingly.

Also, as long as the role hasn't been graded yet, you can delete previous chapters if one seems too long or you thought of a better way to section it out. I did that last time my 'final' introductory empty seemed skimpy compared to the others.
