First and foremost, sorry I don't know much abt the MMORPG which the story is based on, so I am reading it as a new fantasy story. If you find comments not accurate, you can just ignore them.
For the blurb - I do suggest (optional, since I think yours is pretty good):
When Wolver Squad receives an urgent call to action, it's not just another day on the job. A weapon of unprecedented destruction, far beyond anything the Gremlins have ever crafted, is on the brink of unleashing havoc upon Haven. Armed with scant information, the formidable quartet of Blast, Zimthose, Lance, and Balldrick embarks on a perilous mission deep into enemy territory. Their objective: unearth the enemy's sinister plot and thwart it before irreparable harm befalls their beloved Haven.
Yet, amidst this chaos, ominous signs of impending doom, loom larger: knights mysteriously vanishing, a foreboding message from the sage-like Vise, and the ascent of a Gremlin leader whose ruthlessness surpasses all those before him. Blast makes a solemn vow to protect everyone, but as the challenges mount, he discovers that clinging to his ideals in the face of such overwhelming adversity may be an insurmountable task.
What will he choose? Can he overcome all the adversity?
I really like how you include the images and the lore of the story. Yeah I don't understand most of the terms like who's the Stranger, Moorcroft, King Krogmo, Razwog, Herex etc (although to someone who played the game, they would understand it immediately) (although I do hope for some slight explanation for us (non players haha) but it makes the story interesting -The Wolver squad seems like a reliable squad as Kora mentioned.
There's a space btw the opening quote and A - " About time*
Grammar and spelling I think you delivered them quite nicely, nothing to comment there. The description aren't too lengthy. Although some dialogue for me feels a it tad too long.
But, overall I do quite enjoyed this first chapter. Great work author!
