Titor is hella loaded and hella generous with his money, enough to be able to afford allagan technology, hire two guards/servents for his house, amongst other things. His adoptive family are very, very, very successful merchants, and him being a doctor is pretty good pay as well, so double the gil.
I can also back his wealth oocly, so woot (vending is the main reason I am playing the game outside of RP)
