Tales of Tolgard
Steelers are a form of giant arachnid magical beasts. Once under the control of Lolth, these large spiders look somewhat like tarantulas. For a time, Laduguer and the Queen of the Demonweb Pits were allies and she gave control over these creatures to Laduguer’s duergar. While the alliance has ended, the grey dwarves still use these creatures as mounts.
Steeders lack a poisonous bite, attacking with sharp mandibles. Gray dwarves ride steeders using leather saddles. The dwarves use a complex series of prods and straps to control the steeders. Steeders can move on walls or ceilings thanks to a sticky secretion exuded by their feet and can cling to a surface with only a single foot. Steeder saddles are constructed to allow for this. Steeders do not spin webs, nor can they move in them. Steelers can leap up to 240 feet in any direction, even with a rider.
