Steeliest of the dragons
Actually, the elf was initially named Melf, but they changed it (not sure why, we got him before they changed the name).
I played through Quest for the Heartstone, and I seem to recall enjoying it.
Ringlerun the wizard also showed up on the late cover of the PHB
And Warduke was feature in one of the D&D cartoon episodes, where he captured Dungeon Master! Warduke is also the only one who made a return in Dungeon magazine (as a solo 20th level fighter opponent) sometime during 3E. He also has a D&D plastic mini modeled on him.
That is, indeed, the very PHB that I have to this day. I often wondered if that was supposed to be Kelek on the cover of the 2e DMG.
Kelek and Strongheart also made appearances in the cartoon...

Kelek rode/commanded a pack of wolves and was hunting/collecting unicorn horns to increase his power to take out Venger.
Strongheart...he had a golden hammer instead of a sword...buuuut I forget what the storyline was. Something with busting out of a prison?...gods that was a lot of years ago.
Anyway, good times. Good stuff.
