"There are wraiths here?" 

"I think they mean some kind of monster," Delsmiar demurrs. 

"...Oh." 

The spirit nods.

"So what are spectral wraiths and creeping nightmares? Besides monsters." 

Shrug. {i don't know—i've never seen one}

Sigh. "Alright." 

"We should head back to the others. I think they'll probably avoid the shadows, it looks creepy, but they need to know about monsters. --What monsters are there not in the shadows? Or blood." 

{slimes—and zombies—zombies only at night}

It pauses consideringly, then adds, {and other things in the sky and underground and on other islands}

"And the slimes aren't too dangerous. What are zombies like?"

It shrugs again.

"Do you know how dangerous they are compared to slimes?"

{forest spirit might know}

"Okay. Let's get back to the others and find the forest spirit, then." 

Elsewhere and earlier:

Yttren doesn't really expect to find any sensible trees that act like trees or for that matter can be coaxed into acting any way at all, but that isn't stopping him from checking, in between poking at the grass and the soil. The halflings don't seem to expect it either, particularly, but one of the weird not-trees had apples on it, so for the moment they're good.

The grass is reasonably grasslike, although it has barely enough roots to hold it in the ground and doesn't seem to be natively capable of reproducing. The soil would be excellent for growing real plants in if there were any real plants to be had.

A small round woodenish creature steps out from behind a tree and waves a tiny pointy arm.

{hello friends!}

Fortunately Yttren has a small pouch of seeds on his belt. 

The roundish creature is a surprise, though. 

"Hello?"

The halflings pause and look down from their perches in the apple tree. 

It bounces happily on its tiny pointy feet. {am forest spirit!} Bounce bounce. {so many friend! hello!!}

Yttren goes down on one knee to talk to the spirit better. "Hello, forest spirit. Do you know where we are?"

{in forest!}

"...This is a very unusual forest." 

A tiny shrug. {forest is forest. you have different forest? only know this kind.}

"I have magic for plants, and the trees here don't behave like trees back home and I can't make them do anything." 

{tree here is tree here,} the forest spirit agrees. {is not other tree.}

"There's more than one kind of tree here," he says, pointing to the apple tree. Proust waves. 

{is!} it agrees. {is oak and apple in forest! is bamboo and redwood in grassland! is spruce and maple in snow place! many tree. but all tree here is here tree.}

"Do you know what it is that's different about here, that the trees are so different and the grass is so shallow and there are no soil microbiomes and the ground is shaped oddly?"
