The Two-Headed Dragon had been set by Lucreto to guard the passage to Paradise Lost from the Frozen Reaches. Aside from the strength and danger imposed by all dragons, this dragon had regenerative properties that allowed it to regrow its heads. Connor battled it and cauterized the severed necks with his flaming sword, preventing them from growing back.
