Thinking about beasts of Fey a bit, you are fairly sure owlbears are indeed not very rational beasts. They have bad habit of attacking anything larger then mouse that enters their territory and while they were quite aggressive, it is not likely they were under outside control... although their presence on the road that leads from the portal is bit curious, but it might have just been coincidence.

Winding path leads deeper into the forest, remains of ancient lamp-posts set by it, obviously long abandoned. Careful observation reveals occasional ruins by the path, but forest has long won over any civilization here. With bloodshed over, tranquility has returned over the forest path, serene hooting of owl can be heard somewhere in the distance and careful looking reveals pale, lazy glowing wisps of light glowing in strange shades of blue, purple and green floating somewhere deep in the forest. Flowery fragrances can be felt in the air, likely coming from strange silvery flowered wines that hang from massive trees ahead.

Surveying the surroundings, you are fairly sure there is no imminent danger about. You cannot shake off feeling you are not alone in this place, but at least for now, there is no sense of danger in the air...
