Commander Mara Venn wants the four allied forces synchronized before the violet chaos reaches the altar. She will not waste troops on a plan that leaves civilians and wounded soldiers behind.

The party controls the warhorn, druidic totems, arcane beacon crystal, and scroll of rallying. Every contingent knows the Seventh Nexus cannot be held without the others.

• Offer the Tribunal cavalry a protected route through the Central Approach.
• Promise the dwarves their engines will be recovered after the battle.
• Place the druidic totems at the Eastern Rift before attuning the beacon.
• Invoke Celestials of Dawn lore when addressing the Dawnwardens.
• Use the scroll of rallying to erase one cumulative check penalty, then burn it.

• Survey all four zones with Intelligence (History) to form the plan.
• Attune the beacon crystal at the altar’s edge with Arcana.
• Plant and activate the druidic totems with Nature.
• Rally the Dawnwardens with Persuasion.
• Sound the warhorn with Athletics: three short beats, a pause, then one long blast.
• Redirect one contingent after a failure, accepting that its original zone loses support.

• On the first success, Mara Venn stops retreating troops and orders them to mark safe lanes.
• On a failed check, she demands a new assignment and names the zone being abandoned.
• On three successes, the dwarves fire a warning shot that clears the Central Approach.
• On a fourth success, the druids seal a crack and the Dawnwardens begin their advance.
• If the party argues without acting, the cavalry commander takes the Southern Gate and abandons the Engine Bulwark.
