Altars of Elanthia
Here is a listing of all the devotional altars I've come across in my travels. Some are not 'an altar', and some may not be useful for devotional use. However, each has a strong association with a specific Immortal. I have also made a note on ones that are aligned with the pilgrim badges at the time. I do suggest checking back on them periodically, as new ones are often added into the system.
