Tamm remembers seeing what looked like a rift while fighting that spider. Probably with that thing shifting between planes constantly it opened several of them. But it is hard to keep track of direction and orientation in this misty expanse. The creepy apparitions skirting around the fringes of his vision aren't helping his anxiety any either.
Fairly quickly Tamm finds one of these rifts. A spark of color and sound that is clearly not native to this expanse of mostly gray silence. He tentatively touches it and finds that it has no substance. Instead it seems to expand - ever so slightly - as his material substance comes near. He puts his hand into it.
Then quickly pulls his hand back. "Yeow. That's hot." He flaps his hand a bit trying to cool it down. "Plane of fire maybe? Portal to a volcano? In any case, not somewhere I want to be spending much time."
He moves along - trying to go in a straight line following the direction he saw the others heading in. Though that is easier said than done here. He finds another rift and tries this one as well. When he sticks his hand in it, it at least doesn't burn. "Well, here goes."
He grabs his shield and staff and tries to use them to wedge the rift open farther. It doesn't work well. But he does eventually manage to get them through, along with his hands up to the elbows. "Moment of truth," he mumbles to himself. He takes a moment to glance around and make sure that none of these apparitions are trying anything while he is tangled up in this rift. Then he plunges his head into the rift.
Wriggling and squirming, he makes his way through. The boundary between the planes isn't very long, but it is a tight squeeze. After several minutes, he can feel a breeze blowing against his fingers. 'Hopefully no the plane of air,' he thinks to himself, having no breath to spare to try and speak the words.
Another minute of wriggling and he gets his head out of the rift on the other side. At first, all he can see is tree branches and stars. He quickly scans around and finds that he is emerging from a knothole of a tree. A knothole about 15 feet above the ground, from what he can determine.
He drops his shield and staff and hears them thump on the ground below. He checks the tree for branches that he can use to climb down with. The only one that he sees is not at a great angle, but it will have to do. He gets his shoulders free and feels gravity starting to take hold. He tries to guide himself around to that one branch as his lower half starts slipping out of the planar rift. Then he is falling.

He catches the branch as he falls. He dangles from the branch, reassessing things. Stretched out to his full halfling length, he is probably only about 8 feet from the ground now. Tamm lets go and drops the remaining distance, landing with a louder thump than his equipment did. The equipment that he quickly grabs and stows.
Tamm doesn't know exactly where he is in the forest. Surely he couldn't have gone too far. It at least feels like the same forest, so that is good. He shifts to full wolf form - a rather small wolf, only barely larger than a fox. A sleek white and silver wolf with dark ears and a dark stripe down his back and one black sock on a front foot.
Tamm sniffs the air and listens on the wind. He can see the spider webbing scattered around the area. Even more evidence that he hasn't emerged far from where he left. He gets his bearings from the moon and sets off through the forest in a crosswise direction from the path they were taking previously. 'Should cross the trail here shortly. In one direction or the other.'
Luck is with him, and Tamm quickly comes across another pitchfork laying in the dirt. He sniffs around and follows the villager pack.
A short while later, and he can see Aramil and Harper in the distance. He quickly catches up and shifts back to halfling form. "So," he says as he approaches the two, "either of you know what happened to that spider?"
