For page 2, I'm left with two of Charles's constraints: "They have their exits and their entrances," wherein "the sequence must involve dialogue and interaction among multiple characters, with at least one character making an entrance during the sequence and at least one character making an exit," and the "Corrigan," in which "the faces of all the characters except the protagonist are obscured from view."
I'm afraid my extremely rough thumbnails obscure almost everything from view, but I'll put them up here anyway in hopes that they can at least generate some feedback. You'll note that my thumbnails tend to be extremely rough indeed; my usual method is to make even sketchier thumbnails, just placing balloons and figures and saving the real puzzles of composition for when I'm penciling panels on Bristol board. That won't work so well for this particular method of collaboration, though, so these pictures are (yes) clearer than usual. There's no room for legible text, though, so please refer to the script below (keyed to the numbers of the panels in the thumbnail):

1) Stepan: "I—My master said you could draw a map for him."
Arntham: "A map of what?"
2) Stepan: "Of—of I don't know what. He didn't say, exactly."
Arntham (off): "Then how exactly can I help you?"
3) Stepan: "My master said you'd know, yourself."
Arntham: "And just who is your master?"
4) Stepan: "Magister Ipthorin, of—"
Arntham: "—of Wynholme. I knew him well, once..." (new balloon) "Come, boy; to my lodgings..."
5) Stepan, framed in the doorway of a shabby, crowded room, looks over to Arntham at a writing lectern. In the dark background, some pointy ears are just visible—someone's hiding behind a trunk.
Stepan, thought caption (misdrawn as the topmost balloon): "It's so dark here, but I guess that's no hardship to a blind man. But hold on..."
Stepan, word balloon (on bottom): "How do you see the marks you make, Arntham?"
Arntham: "I don't see them, boy. I feel them..."
6) Arntham: "Look here. I grave them on parchment with a blade."
Stepan: "I can barely see the grooves..."
7) Pointy-eared assailant (brandishing dagger, viewed from behind): "You've seen enough! A blade for your grave, Arntham!"
Arntham (pushing Stepan): "Out of the way, boy!"
8) Stepan falls, hits his head on some furniture: WHACK!
Arntham (off): "Aagh!"
9) Stepan crouches over Arntham's body while looking toward the silhouette of a pointy-eared cur in the doorway. Stepan, thought caption: "Still groggy from my swoon...Arntham looks dead...and what's that in the doorway?"
I'm considering a different approach to panel 6. Instead of crouching behind the assailant and looking over to Arntham & Stepan at the writing desk, the viewer could look down from above on the whole room, thus:

The dark blob in the lower left corner is the assailant, moving out from behind his trunk. I'd want to reframe this somewhat so that Arntham and Stepan aren't stuck at the extreme top with the word balloons at the focal point of the panel; I think I can arrange for their figures to be more centrally located.
Anyway, that's what I've got so far. Help me out, folks!
