Hi there. Interesting stuff, nice fleshed out world, but I noticed something as I looked over the Prestige Classes section of your world. You have a even 12 Prestige Classes available, and since your world is otherwise quite detailed, I am moved to assume these are the only Prestige Classes available. Out of those 12 Prestige Classes, 7 are Fighter based, 2 Cleric based, 1 Rogue, 1 Bard, and 1 Fighter/Arcane Spell User. While I don't disparage against the tastes of others, my personal preferances are for the Rogue/Mage variants, and thus, my interest in Layonara waned when I saw this.
If perchance, this is in *addition* to the Prestige Classes available to players from HoTU (I.E. Shadow Dancer, Arcane Archer, Shifter, ect) then please correct me and I will resume my interest in Layonara and carry on with a submission for approval.
