1. Crater Rim (EL 10 or 20)
This area is shown only in the side view of the lair, as given on the map. The rim rises about 800 feet above the surrounding terrain and 325 feet above the lava pool in area 8. Thanks to the glow from the lava pool, characters can see the crater's interior from here at any time of the day or night.
A steaming crater gapes wide at the volcano's summit. The opening is a good bowshot wide and several hundred feet deep. A lake of orange-white magma fills the crater bottom, and tendrils of yellow smoke and white vapor rise from its surface, tainting the air with a whiff of brimstone. Numerous vents in the crater walls emit similar fumes. Even here, the heat from the lava is like a physical presence. It rises in faintly visible waves, like heat from a hot stove on a winter day.
Six very large openings, each 40 feet wide or more, are arranged along the interior of the shaft like steps in spiral staircase. A lip of black, hardened lava lies below each opening.
The characters can linger here for as long as they wish, but any visible character at the crater rim brings a swarm of mephits to investigate.
Creatures: A dozen mephits from areas 3 and 8 come to greet any characters they see here. If you wish to have the characters encounter Sventsorggviresh early, she too is close enough to catch sight of the characters when they reach the rim.

If Sventsorggviresh chooses to maintain the pin, treat it as a normal grapple attack. Pinned opponents take damage from the crush each round if they don't escape.
Frightful Presence (Ex): Whenever Sventsorggviresh attacks, charges, or flies overhead, each creature in a 240-foot radius that has 27 or fewer HD must make a DC 29 Will save.
