Thaumaturge
Wandering. Not lost. (He/they)
250 days seems pretty long for a language/tool proficiency in a fantasy setting, but I guess it must be complete 100% fluency/really solid mastery or something. Also I guess it costs nothing but the time (and living costs, tutor costs, etc. if any), rather than skill points or Feats or whatever, so it's sort of free which is cool.
Training costs 1gp per day, so 250 gp.
