Echo Gates: Ancient City Fast Travel

Players make a gate by turning a vanilla Ancient City portal frame into an active Echo Gate with a Sculk Heart, a craftable item made from an Echo Shard, an Ender Pearl, raw meat and rotten flesh. Once inside a gate, a player sees a list of the other activated gates, and picking one carries them there at once. Gates are built from Reinforced Deepslate in a rectangular frame, similar to Nether portals, and because that block cannot be obtained through vanilla survival, the mod provides ways to acquire or craft it.

Named gates show their names in the destination menu, while unnamed gates show only coordinates. An anvil with a name tag gives an active gate a permanent name. Removing a frame block switches the gate off and drops it from the network, even though the blocks are unbreakable. Mobs, dropped items and vehicles that enter a gate are sent to a random valid gate. The configuration can be tuned in many ways, including travel across dimensions and XP or item costs for each trip.
