Unwilling to support Tavitha, Ember and the Haunted Blade return to the previous chamber to await the gem dragons only to find a weapon of another sort facing them: a tarrasque. As they face the beast Obsidian, Marcus and Tavitha engage Lerelan. The battle above is even for a time, but the battle with the tarrasque goes poorly, forcing Ember and the Haunted Blade to fall back. With the field shrinking, Obsidian begins to lash out at the Orb of Dragonkind directly, damaging it and then causing it to slowly release energy. Unable to stop the inevitable now, Lerelan moves to manipulate the energy as she did thousands of years ago; joined by Tavitha who still seeks her revenge. This allows the group to turn a singular focus to the tarrasque which in turn is attempting to stop Lerelan and Tavitha. Despite the creature’s best efforts, moments later it lay dead on the floor of the chamber and Lerelan and Tavitha were able to complete their work; the later not surviving the process.
