《龍王子 第四季》第5話 The Great Gates

After discovering what Claudia did, Ezran's party (sans Zym) and Zubeia depart for Umber Tor, the residence of archdragon Rex Igneous, to collect the first key to Aaravos' prison before Claudia. Upon arriving at Umber Tor, they find the gate blocked by rubble, but the door guards direct them to a secret entrance within the Drakewood, deep within the Uncharted Forest. Rayla and Soren separate from the others to look for the entrance, but when they come upon an Earthblood Elf bullying a drake, Soren impulsively intervenes on the beast's behalf, only to be captured and thrown into a hole called the Pit of Despair alongside the drake. Aaravos' homunculus guides Viren, Claudia and Terry to Umber Tor.
