a PoL adventure played with DnD 5e

After the Heroes from Winterhaven suddenly vanished it is your turn to show this world what you are made of. Will you succede where they appear to have failed?

And the world does not lack in threats.
The dark forces that kept the Heroes from Winterhaven busy are still at work,
the horde in the south is still on their march towards the north
and rumors about the revival of an old empire come from the east.

In these times the civilized races should work together, but the reality is far from it.
The elves have mostly returned to the fey world and dwarven and human kind can not agree on who is going to lead their combined forces, as so they stand separated.
