There's probably a number of ways to break these pitches up and it appeared some possible variations on some of the pitches. Climb a great crack on the first pitch. Where this crack ends there is a bolted protected the face moves above. With a 60 meter rope you can take it all the way to a ledge where you can belay at the base of a left-facing dihedral. Climb the dihedral and belay at a ledge or continue up another crack before belaying at a ledge left of the crack at the base of a chimney. We thought the next pitch was great. Climb up the steep chimney which you can stay out of by climbing the well-featured face and continue up and right until you come to the large chimney below the summit block of the Warlock. Face climb past some bolts to the summit of the Warlock. If you've been to the Needles you know moderates are in short supply and Imaginary Voyage is a good, moderate route that gets great afternoon sun when it gets hot.
Located on the east or southeast face of the Warlock. Go around the north side of the Witch and past the Howling. Descend the gully between the Warlock and Voodoo Dome. It's been a while, but I remember looking for a crack on the face left o f a large dihedral. There is a bolted face route just right of Imaginary Voyage. There's a descent topo on Clint Cumming's Needles site.
