Okay, after reading through everything, this is what I summarized of what each character was and is currently doing after Mayflower. Confusion spots, or "I say one thing and another thing happened" moments are in [brackets.]
-After Vera and Regal chased after the Hazzling, there were no post made for her saying that she followed until they got back, so I assumed she waited for the group to return. She even just met Arcius when the group returned, so if she was with them she would have know who he was already.
-After the group returned, Anna didn't feel good and Regal carried her to a makeshift raft at the river [despite the fact she ran away in the opposite direction of the group in fear of her doing something horrible So I assume Regal chased after and caught her?].She's currently being threatened by Regal to be put out of her misery for showing symptoms of monster illness.
-Vera followed her Hazzling when it went off on it's own, and Regal followed after her.
-She ran into Arcius, which she and regal treated the arrow wound in his shoulder.
-They returned with Arcius back to the group, and the "Ghost Child" appeared. She asked if anyone else could see it. Arcius said to her that they should go follow Regal, and left hoping that she was following him.
-Regal chased after Vera when her Hazzling ran off. There they found Arcius and together, they treated his arrow wound.
-After arriving back to the group he heard Vera talk about a "Ghost Child". He slung a sickly Anna over his shoulder [who ran away the opposite direction first, and he apparently grabbed her without any chase stated] and took her to the raft at the river.
-At the river, he wanted to put Anna out of her misery, but Arcius ran and tried to stop him. He then decided he would only kill her if she started to turn. He looked at Vera and the "Ghost Child' [who wasn't confirmed to be there yet] and asked Vera to use the pole to guide them across the river [which would normally indicate that the entire group was there, but the only one confirmed to be there was Arcius and Anna unless he planned on leaving everyone else behind. If he did plan on leaving people behind though, he wouldn't of asked Vera anything], because he couldn't turn his back to Anna in her state.
-He saw Vera and Regal going through the forest, chasing Vera's Hazzling. He was discovered however, and Vera and Regal treated him.
-On the way back to Anna and Mahli, he spotted Delivery-Lady Rebecca who was going the opposite direction from them several trees away. he only caught a glimpse and, but he pointed it out, then kept going.
-When caught up with the group, he was introduced to them [by no one specified. Just general I guess]. He then saw the "Ghost Child" and wondered what it is. After Regal left with Anna, he told Vera they should probably follow him and get to safety.
-When he arrived at the river, he saw Regal about to kill Anna and ran to stop him.
Everyone else had 1 to 3 posts so it shouldn't be to hard to understand those. I hope this helped and if I was wrong somewhere, or if there is anything else I can do please let me know.
