Just like Tybalt's, Isaiah's name was taken from Guild Wars, albeit borrowed from a less prestigious character: Confessor Isaiah.

The character itself is a departure from Tybalt's stern, somewhat obsequious personality, Isaiah being carefree and more likely to lead than to obey.

I strongly hesitated between a Guardian of Fire and a "Feeder", to the point I made two versions of the character, but eventually went for the additional muscle. The team did not regret it.
