Nagafen’s Lair
Sol B: caverns deep in Lavastorm where kobolds hold the entrance, bats and bugs fill the tunnels, fire giants guard a temple, and the red dragon Lord Nagafen waits at the bottom.
The dragon’s caverns
Nagafen’s Lair, or Sol B, is a large set of caverns deep in the Lavastorm Mountains. Buried inside is the lair of the fire giants, the personal servants of the mighty dragon Lord Nagafen. Bats and insects infest the tunnels that lead to him, and kobolds have settled in the entrance.
Monsters run from about level 35 to 50 and above: greater and Solusek kobolds and their shamans, sonic bats, lava beetles, lava duct crawlers, lava guardians, imp protectors, and fire giants with their magi, warriors and wizards. Named figures include King Tranix, the Solusek Kobold King, Efreeti Lord Djarn, Magi Rokyl, Warlord Skarlon, Targin the Rock and the Death Beetle.

One of Antonica’s hardest
The EQ Atlas counts this among the two toughest dungeons on the continent. Everything sees through invisibility, so corpse runs and sneaking are out: you fight your way through. The tunnels are winding and confusing, quick escapes are dangerous, and lava does heavy damage; longtime hunters wear whole suits of fire-resistance jewellery.
The kobolds are the easiest foes, which is not saying much. The bats and bugs are worse: the bats stun for a long time, the bugs carry poison and disease and travel in aggressive packs. Deeper, imp guardians surround the efreeti, with almost no safe way out but evacuation.
Fire giants and the dragon
Further on, the fire giants keep their temple. Clearing it takes a skilled high-level team and a long plan: they cannot be mesmerised, can be charmed only by very high enchanters, resist all spells cast from outside melee range, and can be pulled through walls. A feign-death puller is essential.
At the very bottom lies Lord Nagafen himself, protected by everything above. The guide heard of no kill with fewer than four full groups, and fire protection is the price of living. Nagafen was one of the original raid dragons, with Lady Vox in Permafrost.

Entrances
The entrance is on the southern edge of the great lava pit in the Lavastorm Mountains, next to Solusek’s Eye, which also lies nearby underground when you are hunting the kobolds, though the path is twisty. The mountain is the domain of Solusek Ro.
