Re: The Darkwood Inn II (OOC)
By all reports, PF2 works great at level 1 (certainly better than DnD 5E which takes until level 3 to actually get going).
However, I don't think Arell actually 'works' in PF2. "Champions" in PF2 focus on Defense (actually somewhat to their detriment) and Arell is very much offensively focused. Now this can be mitigated (the 'Free Archetype' Variant rule would help tons), but I'd be stretching mechanics to fit the idea in my head, rather than making a character suited to the mechanics.
So, option 1 doesn't really work for me. Option 2 is a little better. The three-year time skip, we could justify changes in equipment and combat style (and Rolf growing to mount size :D).
However, I, personally, am interested in option 3, "something different". Higher level would be nice, but not necessary.
