Lately I've been watching the amazing "Frieren: Journey's End", which for any unfamiliar, features a team of young heros accompanied by a 1,000 year old elf and it got me thinking again about wanting to play a game where one can play a mentor or elder figure like Gandalf or Frieren without overshadowing the other characters at the table. I'm sure there are a few systems that do this, Ars Arcana I believe has such a feature, as does Mouseguard, but neither system is to my taste, so I wondered if others know of RPG's where more powerful characters are not necessarily more important.
