ToME: the Tales of Maj'Eyal

I dont have every type of character unlocked yet and im wondering if the engine has the infrastructure to support the direct control of several characters instead of a single one.

I'm sure it is possible, though there isn't a class that does it. Summoners and Alchemists both can control their minions (in different ways) but not simultaneously with their player character.

There is support to do this with modules. There are a few ways of approaching it but doing this for tome with concurrent actions may be tricky.

Was just thinking of a character that is not a single person.
As in, you do not start of as a single character, or maybe you start of as a single one but than you get a few more characters with you on a permanent basis which are also not allowed to die...
