I am Grendel, Hastur's loyal servant. I am sorry my Master is not here to greet you, but he's given precise instructions. The Master mustn't be disturbed while he is working.

Although I am a fool, I have been a student of his painful school for as long as I can remember, and I offer my humble services to you. My Master loves his toys, Forge and Anvil -- the implements of others' humiliation and ecstasy. I will attempt to offer suggestions, succor and secrets on the use and abuse of his toys.

Forge is the map editor included with Marathon Infinity. Crafted by dwarves at the dawn of time, it inspires awe in the map-makers here at Double Aught. Although Double Aught didn't write Forge, we have used it and its precursors for several years. We offer our help and guidance in using this powerful editor. Grendel is a most obedient guide, so sit back, peruse, and let his suffering be your good fortune.

To learn more about Forge, visit Bungie's Forge page.
Anvil is the most comprehensive shapes, physics and sound editor made. Michael Hanson gets a big round of applause from everyone here at Double Aught, except from Grendel, who's fingers are really sore. He doesn't clap much anymore. We'll have pages dedicated to Anvil coming up soon.
