Questions about Warcraft Story

[MN Lahmar]

Why was Nerzhul forced into making a Blood Pact with Kil'jaeden the Deceiver? (Grom said to Thrall that they gave themselves up willingly on Draenor)
Is Draenor the original homeland of the orcs or did they escape to it after the Dark Portal was destroyed in Azeroth?
How did the orcs encounter the Humans at first time?
How did the Orcish Horde appear? Did they abandon the rest of the orcs and flee in order to live and be freed from the burning legion?
How did Mannoroth and Grom meet at first time?

You should read Rise of the Horde. It answers almost all of your questions. Best Warcraft book out there.

I think Ner'zhul was always power hungry so he made deals with Kil'Jaeden. As the leader as he was among orcs, he influenced them to drink Mannoroth's blood, so they would become stronger.

Yes, Draenor is the original homeland. The orcs devastated it because the blood made them crazy and go into war with the Draenei and civil wars amongst orc clans. Medivh contacted Gul'dan, and helped him open the portals. There were promises of a lush new world the orcs could conquer.

The humans first encountered the orcs in the swamps. There were few at first, but more and more came through the portal.

Grom met Mannoroth when he drank from his blood from the pool in Draenor.

Grom met Mannoroth when he drank from his blood from the pool in Draenor.

Are you sure it was Mannoroth in Draenor?It as his blood?

In Ashenvale, when he drank Manaroth`s blood, Grommash become red.Prior they become green, or more aggressive at least.Fel magic caused their green skin as far as I know.

That's what i'm wondering. When Grom met Mannoroth in Ashenval they already know each other.

First the blood pact took place on Draenor with Guldan's acceptance not Nerzhul's as far as I know. Grom was one of the first chieftains that accepted and drank Mannoroth's blood.

And yes, that's why Grom and Mannoroth already knew each other when they met in Ashenvale!

There is some misconception, "fel magic" is what is in demon's blood that is why demon blood is used for crafting weapons or corrupting conjurers.
They were transformed by fel magic but only because they drank Mannoroth's blood, he was the one sent out to Draenor to corrupt the orcs during the second invasion.
Grom was the first to drink his blood in Draenor that is why he knew him obviously.

Them becoming green as a result would make little sense, since Thrall is green yet he is a direct descendant of Durotan whose clan did not get corrupted.

Either way, there have been many utterly nonsensical retcons since the early games simply because the lore was poorly fleshed out but this is how the official lore stands now. But yeah I think they retconned the green-brown nonsense in warlords of Draenor in a major way.
All orcs were always green in the early games, so was Durotan. He is brown in the new wow expansion all of a sudden.

Humans and Orcs first met at the Swamp of Sorrows, since that is the first place they stayed in Azeroth.

So Grom drank demon blood yet he was still a green in WC2 same with ALL THE ORCS in WC1 and WC2
