Travels Together is a Document in the Rise of the Tomb Raider: 20 Year Celebration DLC Blood Ties. It belongs to the Lord Croft's Journals set and contains a description of the travels to Egypt of Lara's father and his future wife Amelia.
Despite her decidedly proper upbringing, Amelia's taken to roughing it more that I ever have. She fits in and connects with the local populace with such amazing empathy. Because of her, I've had a bit of an unexpected breakthrough in my research. She managed to convince an artifact dealer in old town to sell me a magnificent and quite unusual Tibetan scroll. From what I can tell, it seems to contain details surrounding an immortality ritual of some sort.I think it's time for me to take the next step with Amelia. In fact, I don't think I can wait any longer. I will ask for her hand tomorrow... in the bright Egyptian sun, amidst the dust and ruins.
