y thats a good question. I normally picture him in my head and write him out detail by detail in terms of gender,race, eye color, skin tone, etc. The armors and weapons I sometimes let my imagination take over day 2 day
But do you believe that a high-level character should build a stronghold even at epic levels??
Because most PC's worry that their strongholds will come under siege and its true they require alot of protection of opposing forces and can easily be destroyed with the right abilities/spells.
