The Nether Dragon (Ancient Red Dragon) is an enormous dragon with iridescent black scales. It only comes out to attack during the night.
Researching the Nether Dragon#
If the heroes take some time to research the Nether Dragon, they can learn the following:
A successful DC 20 Intelligence (Arcana) check reveals
that the Nether Dragon loathes sunlight. Any spell or item that can produce sunlight would be very effective against it. A successful DC 20 Wisdom (Nature) check reveals it is
immune to Fire and Necrotic damage.
Orb of Dragonkind#
This secret can be learned through the appropriate spell, but it isn’t contained in any history book.
Centuries ago, the Kraken brought a legendary Orb of Dragonkind to Thylea from another world. The powerful artifact holds dominion over all dragonkind. No dragon, not even the Nether Dragon, can resist its call. When the Orb’s power is invoked, every dragon across Thylea hears its summons and must obey, drawn inexorably toward the one who wields it. Refer to Lair of the Kraken in chapter 3.
