Karthos' Little Green Book

A little green book owned by Karthos The Green, paging through it you see glimpses of what seems to be research, hastily written notes, and to do lists. Some pages even have dried pressed flowers and dried squashed bugs that have notes written around them.

Research Entry - 1489 DR Flamerule, 3rd-Day
Three days into my latest deep forest study in the Neverwinter woods near Blackford Crossing, I awoke with morning dew on my brow and rose with a shiver that I felt through my entire body. It felt noticeably colder this morning than the previous days I've spend in the forest this month, which definitely odd for this time of year.
During my walk-about this morning I looked for signs of cold creeping into the forest, however, everything seems as it should for this time of year -- foliage and plants are reaching towards the mid-summer sky unrestrained per usual. No signs of early foliage or plant change due to cold temperatures.
I spent some time meditating and communing with the forest after my morning walk-about, I sense nothing of ill intent in regards to the early and unexplainable cold in Neverwinter forest. From the trees and winds themselves, I do hear some whispers of unending and unexplainable cold in the North. I do not know much about the North, but it's concerning to say the least. From what I've heard in passing, it's always cold up there. Maybe this whole thing is just the moss and mushroom combo I scrounged up and ate last night.
I should take a nap.

I can't shake the feeling that there is something wrong...something wrong in the North that may steep into the woods of Neverwinter. It gnaws at the back of my mind ever since I awoke yesterday during my forest study, the cold feels as if it's slowly creeping in and freezing my thoughts where they stand.
I cannot stay out here any longer, I must make haste back home.

While on my trek home, I met some druids of the Emerald Enclave. At first thought, I thought this was curious as the Emerald Enclave does not stray into Neverwinter forest that often.
They spoke of odd reports from other druids of the northern forests that involved dreams of their forests flash freezing overnight.
I relayed that I have also had odd premonitions of cold seeping into the Neverwinter forest.
They revealed that they were journeying North to investigate the cause as they've heard rumors of the endless cold plaguing Icewind Dale.
