Leylines

 This mod, heavily inspired by Waystones, allows for the teleportation of players and other entities between specific locations in the world, that must be inferred by discovery and cartography.

While exploring, you’ll come across cairns — unassuming stone structures, built to mark long-forgotten routes. In themselves these are boring, but as you map them, you’ll find they’re located like pearls on a string.

These are the leylines, difficult to locate by modern methods, but known to the ancients that built the cairns. Wherever two leylines intersect in one chunk, a leynode is formed. The potent geomagical properties allows for the operation of three devices:

The leybasin and leymouth (orange and blue pad): Rightclick a chalk on a mouth, then on a basin to bind. Rightclick on any other block to unbind the chalk. Any entity that steps on a bound basin is ‘ported to its mouth.

The handcairn: Simply place and rightclick to open its gui, then choose any other handcairn to ‘port to. Don’t suffocate in a wall (the handcairns preserve your relative position)!

None of these blocks can be placed outside of leynodes, or in any dimension other than the overworld.

The density of leylines, and the density of cairns on a leyline, are configurable.
