Centrespire
The central mountain of Bytopia, and the only one long enough to connect the two islands.
Geography
Localized Phenomena
Because of Bytopia's localized gravity, there is a point around the midsection of the Centrespire where gravity pulls equally between the two islands, and travellers float.
Climate
The midsection of the centrespire is especially cold, both due to its altitude, and due to the constant winds, which nothing is high enough to shield them from.
Fauna & Flora
Because of the constant winds, few creatures live in the midsection of the centrespire, though the usual wildlife populate its lower slopes on both sides. There are a fair amount of caves within, especially on the Shurrock side, where creatures such as yeti, bears, and other cold-tolerant animals and monsters lair.
The bird population is not as abundant as one might expect, as the reversal of gravity near the midsection is disorienting to most flighted creatures.
