Battle of Maveth

"You know, everyone had this place wrong. It isn't death. It's a new beginning. Malick was right. This is all meant to be. And the fact that you followed me here, that we're in this together, that just confirms the fact that I am part of a grand plan. I see that now."

- Grant Ward to Phil Coulson

The Battle on Maveth was a struggle between Grant Ward, Phil Coulson, Leo Fitz and It, when Ward and Fitz were sent to Maveth to bring back It for HYDRA and Coulson followed to get revenge on Ward for killing Rosalind Price.

Background
"Now we're building an army for It to command when It returns, and you and I will rule beside It."

- Gideon Malick to Grant Ward

Thousands of years ago, an Inhuman was born on Earth who was so powerful his fellow Inhumans banished it to the planet Maveth, which it made desolate over the many years it was stranded there. The group HYDRA was founded as a group of It's worshipers, who dedicated themselves to bringing the leader back by sending their members through the portal, though none returned and the people sent through came to be viewed as sacrifices.

In 2001, Gideon Malick began Project Distant Star Return, a new attempt to bring back It by sending four astronauts through the portal who did not know they were being sacrificed. Three out of four astronauts were killed by It while the last one, Will Daniels, survived alone until 2015.

In 2015, Jemma Simmons accidentally entered the portal and was transported to Maveth, where she found Daniels and stayed with him for six months until S.H.I.E.L.D. rescued her. However, back on Maveth, Daniels was killed by the Inhuman while Simmons was rescued, allowing the Inhuman to take over his body.

Later in the year, a HYDRA agent named Grant Ward murdered Phil Coulson's love, Rosalind Price, which made Coulson swear revenge on Ward. Ward also kidnapped Leo Fitz and Simmons to help HYDRA travel to Maveth and return with HYDRA's leader, since Fitz and Simmons were the only ones to return successfully from Maveth. While Ward, his team, and Fitz jumped through the portal, Coulson followed them to the alien planet in hopes of exacting revenge on Ward.

Battle
"How many people? The lives you've taken! It's over Ward."

Aftermath
Alphonso Mackenzie and Daisy Johnson were in the HYDRA Castle when Phil Coulson and Leo Fitz emerged from the portal created by the Monolith fragments. They quickly boarded the Containment Module, abandoned by Lash, and were reunited with their fellow S.H.I.E.L.D. colleagues aboard the Zephyr One, before the Castle was destroyed. Though upset that Will Simpson was not with him, Jemma Simmons was happy that Fitz returned safely. As the two hugged, Fitz gave a weird look to Coulson, knowing that his leader had committed murder for revenge.

It commandeered the body of Grant Ward and also escaped the destruction of the HYDRA Castle; It, now back on Earth, met with Gideon Malick.
