Referencing the raised YAR on panel 2, the first couple cipherletters of K3.  DYAHR is on the same row as the extraneous L.  Combine the two and you can get three options: Hardy, Hardly, L. Hydra.

Googling L. Hydra led us to:

In Greek mythology, the Lernaean Hydra was an ancient nameless serpent-like chthonic water beast (as its name evinces) that possessed 9 heads— the poets mention more heads than the vase-painters could paint— and poisonous breath so virulent even her tracks were deadly.  The Hydra of Lerna was killed by Heracles as one of his Twelve Labours. Its lair was the lake of Lerna in the Argolid, though archaeology has borne out the myth that the sacred site was older even than the Mycenaean city of Argos, for Lerna was the site of the myth of the Danaids. Beneath the waters was an entrance to the Underworld, and the Hydra was its guardian.

The Hydra was the offspring of Typhon and Echidna (Theogony, 313), both of whom were noisome offspring of the earth goddess Gaia.

Upon reaching the swamp near Lake Lerna, where the Hydra dwelt, Heracles covered his mouth and nose with a cloth to protect himself from the poisonous fumes. He fired flaming arrows into its lair, the spring of Amymone, a deep cave that it only came out of to terrorize neighboring villages . He then confronted it, wielding a harvesting sickle (according to some early vase-paintings) or a sword.  The weakness of the Hydra was that only one of its heads was immortal.

The details of the struggle are explicit in Apollodorus (2.5.2): realising that he could not defeat the Hydra in this way, Heracles called on his nephew Iolaus for help. His nephew then came upon the idea (possibly inspired by Athena) of using a burning firebrand to scorch the neck stumps after each decapitation. Heracles cut off each head and Iolaus cauterized the open stumps. Its one immortal head Heracles placed under a great rock on the sacred way between Lerna and Elaius (Kerenyi 1959:144), and dipped his arrows in the Hydra’s poisonous blood, and so his second task was complete. The alternative to this is that after cutting off one head he dipped his sword in it and used its venom to burn each head so it couldn’t grow back.

Heracles later used an arrow dipped in the Hydra’s poisonous blood to kill the centaur Nessus; and Nessus’s tainted blood was applied to the Tunic of Nessus, by which the centaur had his posthumous revenge. Both Strabo and Pausanias report that the stench of the river Anigrus in Elis, making all the fish of the river inedible, was reputed to be due to the Hydra’s poison, washed from the arrows Heracles used on the centaur.

The problems is that HYDRA makes a great keyword but what are we supposed to use it?  The extra L can be used in combination for Lernaean Hydra or by itself.  YAR could also just be RAY backwards.

More questions than answers on this one.
