Pylons

Pylons are furniture items. They allow a player to teleport to any other pylon with the following restrictions:
 * Pylons can only be used when there are 2 or more NPCs nearby.
 * Pylons only work if there are 2 or more in the world. This system is known as the pylon network.
 * Pylons only function when in the matching biome.
 * Only one of each type Pylon may be placed in a world.
 * The pylon network cannot be used during Boss battles or invasions.

Pylons are sold by NPC vendors, and have interactions with the Town mechanic. They require a minimum of 2 NPC's in their preferred biome to be sold. Each specific pylon, is sold by one specific NPC.

Types
Pylons have a corresponding biome. They may only be sold by NPC vendors who are living in that biome. Additional requirements about number of NPCs or happiness of NPCs in the area exist before pylons will be sold.
