Age of Wonders: Planetfall

This is a military empire quest. Empire quests are activated in the campaign automatically or in a scenario by selecting the 'Empire quest' checkbox under 'advanced setup' and 'gameflow' as you set up the game.

Empire Quests can be viewed in game by bringing up the radial menu with the Y button and selecting "Objectives".

To Unlock The Conquerer:
- Conquer 3 dwellings

Rewards (For being first player to finish):
- A small army of racial units appear at the capital colony

Prerequisites:
Complete The Invader
- Kill 2 armies belonging to an NPC faction

Edit: This may be glitched in favour of the player. I unlocked this achievement when annexing two dwellings through peaceful means and annexing 1 through military means in one game.
