Many half-elves perished because they got lost spending long times on the seas far away. The elders found a way to magically set a beacon in the dark for returning if something went wrong. You can only set one beacon at a time. A new one replaces the older.
Usage: 'cast beacon' sets the beacon, 'cast beacon at home' transfers you back to your beacon.
