Proposed Canon

Natural allies (or non-capital sides) are sides in Erfworld that have no capital, no cities and no royals.^Erf-b1-p079a They do, however, have their own treasuries and can form long semi-permanent alliances, or they can sustain themselves via mining, farming, hunting, and such. Rather than using cities, they can pop more units for their side via Moneymancy ^WoT-6051503.

Known natural allies sides:

• Hobgobwins (currently allied to Gobwin Knob)
• Gobwins (previously allied to Gobwin Knob)
• Marbits (former & likely current allies to Jetstone)
• Elves (previously allied to member or members of Royal Crown Coalition
• Witches (at one time allied with
• Daemons

Racial Hatred

Some allies cannot be allied with a side at the same time as other allies.

Elves and Marbits will not ally with a side that has Gobwin, Hobgobwin, Witch, or Daemon allies.
