...Eh...where Can i find...

[MrBoobBlobinSpackle]

The black heart lair?
Or eir?

I'm relevantly new to this game, but I know my way around the novice places to an extent.

In the beginning place, I think the farthest I've gone is Mystrica Hill ...or wherever its covered with gnomes and odd things that Kill you.

And for Essne...eh... Not very far. I usually stop when The angelboo's start to kill me.

Any help?

The maps are VERY far away. From one town to another can be 8 - 24 maps. I suggest just leveling up and then teleport there.

Blackheart's Lair is an event dungeon, it was accessible only in February (Valentine's Day) and April (Easter Day)
You can teleport to Eir at lv 40, or you can run from east of Essene or east of CandyVault, but the monsters in the way will probably kill you. lol
