My home-made campaign world, "Jera", ran through 1992-1993. My players keep referring to those as the "golden days" of our group. And these four characters stood head and shoulders above the rest, as the most memorable PCs our world had to offer.
The Antra (Márcio Fiorito)
This half-elf wizard won the right to bear the Cloak of Darkness and the Staff of Light as the defender of the shadows. With his pseudo-shadowdragon by him, he fought to resist the temptation of slipping into the dark.

Father Jeriash (Léo Lopes)
Originally called "Brother" Jeriash, this human priest of the God of Magic, Manna-Ki, was a lifelong friend of the Antra. His ill-fated love affair with a druid-turned-cleric of Tiamat is as remembered as his long-winded Turn Undead.

Sir William Hadrathus (Rodrigo Landim)
The longest-running of my PCs, this paladin withstood all the "reality shifts" that occurred whenever the DM bought a new rulebook. Through sheer role-playing, he managed to bring Father Jeriash back from the dead.

Torath Whitelion (Many Players)
This barbarian prince was so unbeatable that he refused to go away when his original player left the game. The champion of the Lion Clan, he fought his way through many players before winding up in Piggy's hands.
