Hello movil <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
The dragonheart needs the dragonarmour - you will get a clue for this from the Dwarven King/Dwarven Halls/Dark Forest after solving the Stone Axe Quest (part of the council member quest).
But first go show it to the leader of the Wariors Guild/Dark Forest. <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />
Haven't you found other "dragon" items yet? The heart is part of a much bigger... eh... collection. (don't want to spoil to much) <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
