Serpent's Spine

Description
These mountains, named after the way they look like a winding snake on the map, separate the Deep Forest in the north from Britain and Castle Britannia in the south. They are next to impassable, and hold the entrance to the dungeon Despise in their middle part.

In Ultima IV, the White Stone was hidden in these mountains, while in Ultima V, the Glass Sword was found at exactly the same place.

Things to see

 * Cave of the White Stone (NES Port of Ultima IV)
 * Dungeon Despise
 * Selwyn's Tower (just west of it)

Trivia

 * According to the epilogue of the FM-Towns port of Ultima III, the Serpent's Spine mountains were created during the cataclysm which accompanied the death of Exodus and the sinking of the Isle of Fire.
