what is the lord of the rings one and pokemon ones
The Imperial City quest Unfriendly Competition involves the Macabre Manifest, a catalog of those recently perished. One of its entries concerns an "Oford Gabings", an anagram of Frodo Baggins, and lists several items that Frodo carried during The Lord of the Rings saga, including a "travel cloak with silver and green leaf fastener", an "enchanted shortsword with inlaid writing", a "leather bound travel journal", and a "gold ring with inscription (cursed?)".
In Mudan Grotto there's a skeleton called 'Peke Utchoo', which sounds quite similar to the Pokémon Pikachu. Whoever put the skeleton in also included a note that reads, "If anyone shall ever find me, I hope I am able to bring them to laughter." The note was probably put in to make sure that the player realizes that the skeleton is meant to be a joke.
Encountered during the Main Quest, there are a few locations which reference Pokémon in their names. In Ilunibi, there's a section called Marowak's Spine. In Arkngthand, there's a Weepingbell Hall. In the Urshilaku Burial Caverns, there is a section called Kakuna Burial.
