It was 7am game time, was dinking around until night and killing things. Noticed that there was a dread wolf, killed it and got the page. So, it appears you don't need to wait until night.
Stand in Kith at 1559, 19, -22 at night and you'll have 3 or 4 of these in no time, assuming you are high enough to handled being swarmed by the undead denziens of the night.
Well, I came to Kith a couple nights ago, and just before it went night in EQ, I went LD. Figuring it wasn't worth it to wait (I was quite tired), I went to bed and came back the next day.
I logged on, and it was already night. So I quickly summoned bags, food, bandages, pet stuff (useless weaps and armor), etc. Got my pet out and went hunting. Found a dread wolf (lblue at 50) almost immediately and pulled it back to the WC zoneline. My pet dropped him fairly quickly after buffing ;), and he dropped the Magi'kot pg. 1.
Theres me thinking "Well the guy said spawns off an Enraged Dread Wolf , so i'll kill everything to get them spawn and not bother looting in case I get attacked, and only loot the Dread Wolves! Great idea!!" . Well, luckily I looted a dread wolf because I had a fuzzy feeling (:p) and it dropped! Also got some Druid / Ranger cloak from an enraged dread wolf.
Try to avoid the clerics at around 50, post 55 you'll be fine. Woot!
In addition to the dread wolf and enraged dread wolf, there is also a dreaded wolf in Kithicor Forest. I got my Torn Page from one of them. kiscorliana seems to have it right, although I don't know what other kinds of wolves there are. I recommend the area near the West Commonlands zone canyon; I saw several dread and enraged dread wolves there (that didn't drop my page) in addition to the dreaded wolf that dropped my page for me.
