As stands your character has 90GP to equip himself with, which is a bit of a problem as a suit of plate mail costs 100 gp in this world.
But... I do like your character concept. And - as you were so kind as to provide a pdf of the VFW story for everyone - I was considering giving your PC a gift anyway.
So have the plate mail on the house! It's old, battered and unlovely to look upon, and many comelier knights will no doubt offer Sir Owen their scorn, but it still does the job, and that's all that matters.
What else do you want your guy to have?
Wow, thank you very much, Doc! (I had not noticed this message, earlier.) I am good with any of those options; basically, what the character needs to work is a closed helmet, but the plate mail is not necessary if it's too expensive. Otherwise, he ´doesn't need more than a worn-out cavalry mantle, a few items of everyday use, as well as sword, perhaps a shield, and perhaps a cavalry spear. --- And, no worries, no thanks needed for the file; it's an honor to play with you all!
