"How are there so many orcs here??"
"Drekeen! Hard turn!"
"Dead end. Trapped by orcs and Drekeen. Prepare to fight!"
"They're ignoring us? That's a general! And he's going right for the orcs!"
"Nothing but an orc horde this way. Form a line here as well."
"There's nothing back here general! Just an open pit to be trapped in by orcs to die!"
"Emperor, we have a landing zone. We just need to hold against the orcs on one side, the Leweans on the other, and clear out this squad to secure it."
"Very well, dispose of this squad while I oversee the Lewean front. Good luck General Sabino."
"We hold for the Emperor!"
Emperor Tiberius Auralnus himself in his ill-fitting armour is accompanied by two Dragon Priestesses (Heros), a Dragon Trainer (Hero), and his Squire flagbearer on the Lewean Front.
Better angle of the Lewean front.
The first line at the orc front
Sir Wildswing the Strong (hero) leads the orc front.
Better angle of the orc front.
Orc second line.
General Markus Sabino leads the force in the center.
Better angle of the center.
The poor squad who needs to hold off the entire might of the Drekeen Empire. They have a ranger captain hero.
Secure the center pit to allow your dragons to land after 9 turns.
Do not allow the Emperor's flag to fall.
The Emperor must survive.
Orcs: Prove you are the greatest. Kill the leaders of all enemies.
Ensure all orcs at risk of dying of old age die from enemy action.
Leweans: End the war. Kill Emperor Tiberius Auralnus.
Hold the center.
Orc and Lewean units constantly enter at their banner. (2 squads/turn ish).
Each army can do one heroic feat per turn per front that they "occupy" (All three for Drekeen, Leweans get their entrance and the center, orcs get the side.) Unless of course narrative reasons.
Cliffs are to steep to climb, the only hope for the Emperor against the undending tide of enemies is the inbound dragons extracting him.
Initiative order is re-rolled every round until just two factions remain, then they just alternate.
The mouintainous terrain prevents the usage of cavalry.
