Rotate Character towards direction in Local Space

I am making a game on a 'Grid system.' Each time the player hits WASD, I keep track of the direction as either a Vector forward, back, left or right.

From this point, I wish to cast a ray towards the position of the grid block, rotate the character in that direction, and then walk forward.

The code I am using right now is:

public void Move(Vector3 direction, bool faceDirection, bool canFallOffEdge, bool force) { c.t.localEulerAngles = new Vector3(); c.t.eulerAngles = new Vector3(); Vector3 destination = c.t.position; if (!c.state.canAct && !force) return;

             if (direction.x < 0)
                 destination -= new Vector3(1, 0, 0);
             if (direction.x > 0)
                 destination += new Vector3(1, 0, 0);
             if (direction.z < 0)
                 destination -= new Vector3(0, 0, 1);
             if (direction.z > 0)
                 destination += new Vector3(0, 0, 1);

             destination = c.t.TransformDirection(destination);

             Debug.LogWarning(direction.ToString() + " / char pos: " + c.t.position);

             Ray ray = new Ray(destination + new Vector3(0, Utility.raycastHeightOffset, 0), Vector3.down);
             RaycastHit hit;
             Physics.Raycast(ray, out hit, float.MaxValue);
             if (hit.collider == null)
                 return;

             Ground g = hit.collider.GetComponent<Ground>();

             if (g == null)
                 return;

             if (!g.IsEmpty())
                 return;

             c.t.LookAt(g.transform);

             // Move to the point
             //isMoving = true;
             //c.StartCoroutine(Move_Routine(hit.point));

         }

While rotated towards 0,0,0, this works, however it does not respond to directionals.
