dragon vs archerss

The boar is from barbarian.

Undead dragon in the sky (his wings look unhealthy).

Arrows from archers? They look different, archers' arrows have a red end. It can be from nomad or from Niathi. I don't think they are from huntress or arbalester, because their arrows are shorter.

Pikes in the front. Or are they arrows? Anyway, they don't look like pikes that pikemen have, and they don't look like arrows that archers, nomads, Niathi, huntresses or arbalesters have. They look like pikes that Crusaders have (castle guard).

No idea who has a red symbol. Only Pegasus has a red flag, but it's different.

I'm new to this game and I don't have all Eldritch units, so maybe some stuff is from them.

pikemans vs niathi

The lone boar shows that a Barbarian was shot with arrows and killed

No fathers from the tip of the arrows, so a Niathi is ruled out. The top of the arrow is shaped into a star, and the tip is straight. The are also no signs of beatification on the weaponry tip, a handwork of the ravenwood is ruled out, Archers out; their forges are known for excellent metal works. 

These leaves the Nomads, huntress and the Arbaleter units which use bows.

the position of the arrows, they are pointing up, which means they were shot from high ground. So the dwarf fall short, very short. 

So the Huntress and the Nomad remains. Someone has taken great care not to kill the boar. What we know

-Nomad are escorts of a great Goddess Dana a god borne of the roots of a tree, a tree huger really
- The Huntress are priestesses of Mara, a sacrifice loving goddess. 

So the huntress is out, She would have killed the boar, after killing its master. 

These still doesn't explain the flags, but definately a battle between a Barbarian and a Nomad 

It is time to announce the result of our competition!

2,000 Sapphires are going to KENTCNEAL!
