This wickedly massive blade has seven indentations. The first glows with a faint red light. The second glows with a soft green. Both sides have ridged smaller blades extended from the side. The sword depicts thousands of etched soldiers warring along the blade and hilt. If you look closely and concentrate, they almost seem to move. 

According to legend, seven of the most powerful individuals ever to have existed have trapped fragments of their soul in this blade for others to use. Currently only one of these souls still resides in the blade though it is possible to find the others.

First Soldier's Soul: This soldier left a piece of her fiery rage in the form of a fire elemental. Once per long rest you may use your action to summon and control a fire elemental. It takes its turn in initiative immediately after yours.

Second Soldier's Soul: This soldier left his clever tactics in the form of a Will-O'-Wisp. Upon receiving necrotic or fire damage, you may use your reaction to summon and control a Will-O'-Wisp. It takes its turn in initiative immediately after yours. 

Third Soldier’s Soul: This soldier left his cruelty in the form of a curse. When a target fails a saving throw within 30 ft of you, as a reaction you may summon and control a mummy within 5 ft of you. It takes its turn in initiative immediately after yours.

Proficiency with a Greatsword allows you to add your proficiency bonus to the attack roll for any attack you make with it.
